摘要

The prevention of environmental pollution, and waste generation in agricultural production has led to the re-evaluation, and reuse of harvest residues, and agricultural raw materials. Materials obtained by utilising these plant wastes have been shown to increase the organic matter content of the soil, and are used as growing media. This study investigates the effects of compost, cocopite (coconut fibre), and perlite on yield, and quality in pepper cultivation under soilless agriculture conditions. The study utilised 9 distinct growing media: (2:1) cocopite: perlite (Control) (C); (2:1) tomato compost: perlite (TP); (2:1) apple compost: perlite (AP); (2:1) grape compost: perlite (GP); (1:1:1) tomato compost: cocopite: perlite (TCP); (1:1:1) apple compost: cocopite: perlite (ACP); (1:1:1) grape compost: cocopite: perlite (GCP), and (1:1:1) apple: tomato: grape compost: cocopite: perlite (ATGCP); (1:1:1:1) apple: tomato: grape compost: perlite (ATGP). The highest marketable yield was recorded as 459.80 kg/da in the apple compost: cocopeat: perlite treatment. Utilisation of compost resulted in a 30.82% increase in marketable yield compared to the control. Among the other treatments, apple: perlite, and grape: cocopeat: perlite were found to be the most effective in terms of vitamin C content, and titratable acidity (TA), respectively. Conversely, pH, chlorophyll index, and water-soluble dry matter content remained unchanged. Consequently, it was determined that compost derived from tomato, and particularly apple pulp, can be effectively employed in the soilless cultivation of pepper, demonstrating enhanced efficacy compared to cocopeat, a commercial growing medium.
